Version 2.0.

- Organize chats into Chat Folders if you have too many chats.
- Create custom folders with flexible settings,
or use default recommendations.
- Pin an unlimited number of chats in each folder.
- Switch between folders in the new side bar
to easily access all of your chats.
- Send :dice: to any chat to try your luck and get
a random number from the animated dice.
- Send :virus:, 🤒, 😷,
🤕, :sneeze:, :sick:, 🧼 or 🚑
to try out the new animated emoji.
